BALTIMORE — The Yankees entered this weekend targeting a start for Ivan Nova, a former rotation mainstay, at some point this week in Minnesota. But after Nova threw 5⅔ innings of emergency relief Saturday night, manager Joe Girardi indicated the team will keep the current rotation.

So Andy Pettitte will start Monday, followed by Phil Hughes, CC Sabathia and David Phelps. Girardi was unclear about when Nova might make a start. When the team decided to keep him on the roster, it was so he could make a start during the current stretch of 20 games in 20 days. That day has not been publicly determined.

“I thought [Nova] pitched okay,” Girardi said before Sunday night’s game against the Baltimore Orioles. “I just [want to] keep guys in rotation for now. We’ll see. Maybe slot him in somewhere else. I’m not sure.”

It leaves Nova as a man floating without an exact role in the bullpen. He is not a starter. He is not a late-inning reliever. He is not the long reliever — that title still belongs to Adam Warren, even if Nova picked up the slack after Phelps’ meltdown Saturday night.

In 5⅔ innings, Nova allowed six hits. But only one involved a major mistake. He hung a curveball to Orioles masher Chris Davis, a man with ferocious power, in the midst of a season where he crushes hanging curveballs. He launched a two-run homer, his second of the night.

Despite recent success from Nova, he hasn’t cracked into the top five. And one of his highly touted counterparts might not, either. On a Double-A diamond Sunday in Binghamton, N.Y., Michael Pineda stumbled in a rehab outing. He gave up four hits, walked four batters and gave up four runs in three innings.

He threw only 67 pitches.

“I guess his velocity was fine,” Girardi said. “But from the box score, it looks like he didn’t pitch as well.”
